MacroAmes1 98/100 — Ames-test i petriskåler uten glukoseplater (OECD TG 471)

Kun til forskningsbruk. Ikke til bruk i diagnostiske prosedyrer.

MacroAmes1 98/100 is a ready-to-use traditional Ames mutagenicity test kit in Petri dish format — without minimal glucose plates (glucose plates sold separately as AS02-390-MG). 2-sample complete kit with S. typhimurium TA98 and TA100.

In the Ames test, Salmonella strains with his⁻ auxotrophy cannot grow without histidine. Only strains that undergo a back-mutation (reversion) to his⁺ prototrophy form colonies on minimal medium. A mutagen causes an increase in revertant colony frequency proportional to its potency. Revertants are referred to as "revertants" — their count versus spontaneous background determines mutagenic index.

• Traditional plate Ames test per OECD TG 471
• TA98 (frameshift) + TA100 (base-pair substitution)
• Includes PB/BN-induced rat liver S9, positive controls, and soft agar overlays
• Minimal glucose plates sold separately (ref. AS02-390-MG)
